Simplified Architecture for a Cellular Network
June 8, 2021

The device connects over the Radio Access Network (RAN), which defines and manages the radio link between the customer device and the rest of the network. The RAN comprises cellular base stations (BTS in 2G, NodeB in 3G,eNodeB in 4G, and gNB in 5G), wired or wireless links, and a baseband unit that processes the […]

Why Open RAN is Important?
June 3, 2021

If we’re talking about RAN Market Status, The mobile RAN equipment market (covering active base station equipment and antennas, but excluding power supplies, cable, install costs, civils, passive antennas, etc.) was worth about $33 billion in 2019, according to Omdia, and is forecast to grow to $36 billion in 2023.  So the R&D in different […]

This is the last update for the 5G Commercial Live Network in the Middle East till 25th, May 2021 Let’s see the status of 5G Live Commercial Network in the Middle East Saudi Arabia: In June 2019, STC became the first operator to launch 5G commercial services in Saudi Arabia. Zain’s 5G network also went live […]

What is DSS or Dynamic Spectrum Sharing – Part 2
May 11, 2021

As we discussed in the last article, let’s Recap again What is DSS and why we need to use the DSS feature in 5G Roadmap deployment. Due to the occupation of its FDD-based spectrum assets, service providers are forced to choose between the acquisition of a new spectrum or refarm spectrum already in use. Both […]

What is DSS or Dynamic Spectrum Sharing – Part 1
May 6, 2021

Before start talking about DSS or Dynamic Spectrum Sharing, let’s address the problem first and how DSS can solve it. As we know that 5G can support newly released frequency bands for use – such as the C-band (3-5 GHz) and millimeter wave (mmWave) band (24-40 GHz) – are higher than the current 4G frequency […]

What is the difference between Traditional RAN and Open RAN?
April 16, 2021

Open and virtualized RAN, Open vRAN refers to a disaggregated approach of deploying virtualized mobile networks by using open and interoperable protocols and interfaces, implemented over a common propose hardware in a multi-vendor software environment, allowing increased flexibility over traditional RAN architectures., aiming to provide OPEX and CAPEX savings while fostering innovation. Traditional RAN Protocol […]

What is the difference between 4G Core and 5G Core?
April 15, 2021

In LTE Core Network, all data plane traffic must go through a single node type called Packet Data Network Gateway (P-GW). This centralized architecture is advantageous in terms of operation and management. Yet, it could potentially pose a severe limitation when there is a huge amount of backhaul traffics in 5G. The following figure illustrates […]

Functional Split Options for 5G Networks
April 5, 2021

Functional Split Options for 5G Networks As network architects work to meet the 5G challenges of increased traffic and data flows, a fundamental question is how much intelligence to put near the antenna versus at the DUs or CUs. Mobile Network Operators (MNOs) as well as industry-standards groups, such as the 3GPP, IEEE, Telecom Infra […]

Function Migration from 4G to 5G
March 10, 2021

5G shouldn’t be seen simply as the next generation of mobile communications. It’s a smart ecosystem that’s ready to catch new innovations and highly customized services. 4G to 5G Interworking 4G LTE and the 5G networks will continue to interwork for a number of years. This is why it’s essential to:  Support a seamless handover […]

Why do MNOs struggle to shift to Open RAN?
March 7, 2021

Why do MNOs struggle to shift to Open RAN? I know many MNOs are struggling to shift their RAN strategy to OpenRAN in their 5G Roadmap due to many reasons like they can not get away from their monolithic supply chain from the big vendors. Also, there’re some interfaces that are still NOT open even if these […]

What Determines The Capacity Of A Network?
February 17, 2021

In the early 1900’s two researchers working independently derived a relatively simple equation that serves as a Moore’s Law for the wireless industry: the Shannon- Hartley theorem. This theorem gives an upper bound to the amount of information that can be transmitted over the wireless channel where the individual channel capacity is dependent on only […]
